Hello all! Im just a guy whos taking a basic statistics course and came across a phenomena that interested me. Probably very basic, but i cant figure it out by myself. Was messing around on my TI-84 the other day, and ended up just pressing "solve" on a binomial probability function where the probability of the events were the answers of the previously performed function. I don't know exactly how to explain it, so i'll just write it out: (10 nCr 1)(ans^9)((1-ans)^1) weirdly, i kept getting numbers around the same values, so i put the equation into excell and ran it a thousand times with a random starting number (0<x<1). strangely, no matter what the first number was, the answers always tended to the same four numbers, in the same order: 0,385203336 0,048336317 0,30947461 0,110469374 What gives? Nothing about this in my textbook, and i dont know where to start searching on the internet. An explanation or link to related theory or anything that will alleviate my puzzlement would be much appreciated. Thanks y'all!
